Multiple types of video formats can be used with fiber optic technology. This includes 4K(UHD), 12G/3G/HD/SD, DVI and RGBHV video formats as well as DVB-ASI, ATSC, NTSC, SECAM, and PAL. Add to that audio, return video, IFB video, intercom, sync/genlock, timecode, tally and all sorts of data, including remote pan/tilt/zoom control that must run between cameras and the monitoring station where video crews do camera set-up.
Railway operations and control networks are complex and undergoing changes similar to other critical infrastructure industries such as the introduction of microprocessor-based relays and more data points and security to enhance safety and control of the railway. The communications networks that serve them are evolving just as rapidly and require equipment that can function in harsh environments and integrate with generations of rail devices including: Remote terminal units (RTUs), Vital controllers, Control points, Generators, Temperature sensors, Cameras, Emergency phones, Wheel counters, Wayside interface units, Positive train control.
Electric power system is one of the most important achievements in the history of human engineering science. It is an electric power production and consumption system composed of power generation, transmission, substation, distribution and electricity consumption.It will be the nature of the primary energy into electricity through the power plant power generation, transmission, substation and distribution of electricity to the user.With the development of computer technology, communication technology and control technology, the traditional control field is undergoing an unprecedented change and is beginning to develop towards the network direction.The demand for large data and high speed transmission, such as image and voice signal, has given rise to the combination of Ethernet and control network, which is popular in the commercial field.
Smart City is a very large and comprehensive management system. It not only needs to meet the needs of public security management, urban management, traffic management and emergency command, but also takes the needs of image monitoring in the aspects of early warning of disaster accidents and monitoring of work safety , But also consider the integration of alarm, access control and other supporting systems and the linkage with the broadcasting system. The establishment of a smart city to improve the management efficiency of managers and emergency handling capabilities, but also for people's lives and property safety play an important role. Most of the smart city monitoring points are outside, the environment is harsh, requiring products with moisture, lightning, shock, dust, wide temperature work, stable POE power supply and other functions. Monitoring points at the same time the distribution of a wide range of larger, with long-distance transmission, anti-electromagnetic interference and other acteristics.
